[3] Conley, born in 1980 in Doylestown, Pennsylvania,[4] graduated from Central Bucks High School East in 1998[5][6] and received his bachelor's degree from the University of Notre Dame in 2002.

[10] He served as the research director at Portsmouth Navy Department of Emergency Medicine prior to his assignment to the White House Medical Unit.

At first, Trump began self-isolating in the White House, but under the recommendation of Conley, he was transferred to Walter Reed National Military Medical Center.

[24] In an October 4 press conference, Trump's medical team said that he was "doing really well" after his oxygen level dipped the day before and after he was given the steroid dexamethasone, which works by reducing inflammation in the lungs.

[25] Asked if CT scans showed pneumonia or lung damage, Conley said, "There's some expected findings, but nothing of any major clinical concern."

[26] When asked why he was reluctant to disclose that Trump had been given oxygen during the October 3 briefing, Conley stated that he did not want to "give any information that might steer the course of illness in another direction" and "it came off that we're trying to hide something, which wasn't necessarily true.

"[27] White House director of strategic communications Alyssa Farah later stated that it was "a common medical practice that you want to convey confidence, and you want to raise the spirits of the person you're treating," while also asserting that Meadows' anonymous statement to reporters was intended to "give you guys more information just to try to be as transparent as we can".

According to the Associated Press, "then-White House chief of staff Mark Meadows said at the time that Trump's condition was worse than Conley had let on".

[34] Newly inaugurated president Joe Biden announced on January 25, 2021, that he would appoint Kevin O'Connor as the White House physician.
